Couple of months ago I replace the motor inside my Rheem Compressor. Everything worked great for awhile. Today we had a power failure and when I came home the inside temp was 89 degrees. The compressor is coming on but the fan is not turning. The compressor will come on for awhile and then a hissing noise will occur, I am assuming it is a release valve. Can you give me a suggestion on how to check the motor to see if it is bad again. Or could it be some kind of relay inside?
Thanks Shane

If inside coils frosted, turn on fan only, NO COOL then try again when defrosted.
If not frosted, wait maybe 10 minutes then try again. Could have had Surge or Spike.
Not usual both fan and compressor go at the same time. Check voltage out from
Compressor contactor. Maybe load of faulty one dropping voltage to other. Would try one at a time. Or amprobe and meter can help.

Thanks for a quick reply. I just went out and checked and I found no frost. I tried it again and the compressor kicked in fine and once it stopped the motor moved only about 1/2" and stopped. It sounds like there is juice getting to it. It just won't turn I am afraid it may be the motor again. What do you think?

Have you checked the capacitor? WIth unit on take a long handle screwdriver and spin the fan. Use care in doing this. Did the fan work after doing this? Also look ant all wiring connections. Are they OK and not burnt at connections?

If the fan spins freely, I'd say you may have a bad capacitor.

Sorry esquire, we most of posted at the same time.

At least we are thinking on the same line

True, what did you think of that clown on here lastnight? He gave us both red dots I see...

Doug,
I did what you said and the motor started to turn at a slow rate. There are no burnt ends on the wiring, but I did have what looks like a loose connection where the prong attaches to the capaciter. What do you think?

I have another capacitor that will work with the motor my only problem when I replaced the motor it could be wired for either direction. The new capacitor had less prongs on it than the old capicitor. How do I install it with less prongs or is it the wrong capacitor?

Did the cap have a bulged top or look distorted? I'm still thinking the cap is bad. Not expensive to replace. Not ruling out the motor but I'd try the cap first. Do you have a miltimeter?

I think there is a little leaking not much though. Cap looked fine other than the loose prong

The old capacitor was a dual, the new is a single... Simply pull the fan wire from the old capacitor install it on one side of the new, run a jumper wire from "c" on the old capacitor and attach it to the other side of the new, or you can just purchase a new dual capacitor, with the correcting rating of course.

I don't mine red dots when I give wrong advice. Heck, I learn something new everday and sometimes don't read request thourghly and answer too soon. I don't know where he came from but in one post I answered to him he said he had a liitle knowledge, but he didn't even know how to check a coil on contactor, then all of a sudden he has 15 yrs experience and knows everything.lol

That guy got under my skin a little, he started rude. The guy obviously was looking for an argument.

Direction needs to be so it blows air out top. (reversing 2 wires will correct this).
If it had 3 prongs, replace with 3 prongs, unless you know otherwise.
IMPORTANT, With disconnect off, does fan spin freely?

Sorry to hear about the red dot idiot. They usually have less than 10 post.
Seen good advice from both of you, we know who...

Update, Saw that the guy, that gave you red dots was meant to be green.

Before replacing fan motor, Test with good capacitor. It is cheaper.

When I first installed the motor, air was forcefully coming out of the top. However it seemed when I pushed the fan with a long screwdriver is started to turn in the opposite direction. Could this be possible or am I crazy? I will pick up a capacitor tomorrow and check that first.
Thanks

Well, I think your not crazy but try the new cap and see how things go. Many times when I look at something too long and can't figure it out, I just have to get away from it for a while. Come back later and it's an easy fix.You did state that there was some leaking of cap.

Yes, there is a little bit of leaking, so I will get a new capacitor tomorrow and try that. Will let you know tomorrow. Thanks
